AUTOMATIC EJ'ECTOR FOR BOTTLE-LABELING MAGHINES.'

-App1ication filed October 1,1927. Serial No. 223,360.

This invention relates to means for automatically ejecting bottles, especially vials,

from a bottle labeling machine after the labels have been applied thereto.

In machines of this character the vials are fed to and removed from the machine manually, which necessarily'makes the operation slow.

. The principal object of this invention is to speed up the production of the machine by automatically ejecting the bottles, and thus relieving the operator of one operation. v The operator is required merely to feedthe vials to the machine.

Referring to the drawings:

Fig. 1 is a front elevation of my invention, and illustrates sufficient of a bottle labeling machine to demonstrate the utility of my invention as applied thereto; a

Figure 1 is a continuation of Fig. 1;

Fig.2 is a View similar to- Fig. 1, and illustrating the elements of the machine in a subsequent position;

Fig. 3 is a side elevation of the mechanism shown in Fig. 2; I

Figs. 4, 5, 6 and 7 illustrate the various labeling and ejecting operations, Fig; 5 be ing asectional elevation taken on the line Fig. 8 is a perspective view of a detail of the machine.

Fig. 9 is a front elevation of sufiicient of a bottle labeling machine of the type to which my invention is especially adapted, tO'llltlS- trate the mechanism by which the various elements of the machine are operated, the

greater part of the frame of the machine having been omitted for the purpose of clar ty;

Figs. 1O, 11 and 12 are sectional elevations taken on the lines 1O '1O, 1111 and 12-12, respectively, of Fig. 9, these views being drawn on areduced scale relative to that of Fig. 9. V

In machines of the type to which my invention is particularly adaptable, the vials a are manually placed on a supporting anvil 1, a label. depositing arm 2 then places a label m, which previously has had a coating of glue or similar adhesive material applied thereto, on the vial a (see Figs. 1 and 4t) and immediately an arm 3, having a holding shoe 1 thereon, descends, the shoe engagesthe label w pressing its center tightly against the vial a, while the depositing arm 2 moves away from the vial to the position shown in Fig. 2.

A ,pair of wiper arms 5, '5' having resilient wiping tongues 6, 6 thereon are moved from the position shown in Fig. 1 to that shown'in Fig. 2, wherein the tongues 6, 6 engage the opposite ends of the label (see Fig. and

as the arms 5, 5 continue their movement the tongues 6, 6 wipe the said label around the vial in the manner illustrated in Figs. 5 ands.

The operator is then required to remove the labeled vial and place an unlabeled one in its place on the anvil 1.

My invention'relates to means forautomatically ejecting the labeled vial from the anvil, and consists of a blade which is rigidly secured at one of its ends to the label holding arm 3. Thisarm, as is apparentfrom the drawings, is pivoted at 7 and receives a rocking motion. As this arm moves from its label holding position to various positions, including that shown in broken lines in Fig. 1, the free end of the blade 10 moves toward and then strikes the labeled vial' (see Figs. 6 and the impact causing the vial to 'fall over the longitudinal side edge of the anvil 1 into a receiving hopper 11,'wh'ich is secured to the rigid portion 9 ofthe machine on which the anvil 1 is mounted.

To facilitate'the feeding'ofthe unlabeled vials to the anvil 1, I 'mount on the rigid portion9 of the machine a feeding tube 12 which is cut away, as at 13, to facilitate the placing ofthe vials in the tube.

When the ejecting'blade -10'removes a labeled vial from the anvil 1, the operator merely places a new vial in the cut-away portion 13, of the tube 12, and by pressing the new vial inwardly advances a previously inserted vial fromthe rear end of the tube 12 ontothe anvil 1 and continues to press the new vialv until the "vial now advances onto the anvil engages an adjustable stop Mon with legs 17,17 formed integral therewith,

and is provided with feet 18, 18 which reston the rigid portion '9 of the machine, being secured thereto by means of bolts 19, 19.- On one of the legs 17 is integrally formed a bracket 20 in which is provided a screw 21, a

which forms the adjustable stop 1 1 above referred to. A locking screw 22 secures the stop screw in its adjusted position. The longitudinal side walls of the bar are cut away between the legs 17, 17, as shown at 23, permitting the ejecting blade 10 to engage the vial.

The ejecting blade 10. is composed of two sections 10 and 10 for the purpose of perniititng adjustment of the blade. The section 10" is secured to the label holding arm 3 by means of a bolt 25. Each of the sections 10 and 10 is slotted as at 26 for the reception of a securing bolt 27. An aligning element 28 is mounted on the bolt 27 and is provided with side flanges 29, 29 between which the sections 10 and 10 are positioned, thus the section 10 can be adjusted longitudinally on the section 10 and the whole secured together as a rigid element by means of the bolt 27. Thefree end of the section 10 is offset as shown at 30 in order that the blade will engage the vial approximately at thereto. One side of the interior of the hop- I per 11, one side of the spout and the end plate 34: are each provided with a lining composed of resilient shock-absorbing material 35, such as felt, against which the vials strike when ejected from the anvil 1, thus preventing breakage of the vials. The spout 33 delivers the vials into any suitable form of receptacle 36. a

The feeding tube 12 is provided with suitable legs 37, 37 having feet 38, 38 which are secured to the frame member 9 at one end of the tube by means of a screw 40, and at the other end by the screw19 which secures one of the feet 18 of the anvil 1 to the frame mem-' her 9, this foot 38 of the feeding tube being positioned on top of the said anvil foot.

As illustrated in Figs. 9 to 12 inclusive, the label depositing arm 2, the arm 3 which carries the holding shoe 4-, and the wiper arms 5, 5 which carry the wiping tongues 6, 6, are operated in timed relation with respect to each other from a common operating shaft which is rotatably mounted in the frame of the machine and is continuously rotated by any suitable power means, not shown.

As shown in FigsQ and 10, the label dcpositing arm 2 is pivotally mounted on a shaft 51 carried by the frame of the machine and has a rearwardly extending arm 52 which is operatively connected by a link to one end of a lever 5 1, thecpposite end of.

which is pivot-ally mounted on shaft 55 carried by the frameof the machine. Intermediate its end-s the lever 54 is provided with roller 56 which bears against a cam 5'? secured to the main shaft 50, a spring 58 causing the roller 56 to follow the contour of the cam 57 and thereby elfect operation of the label depositing arm 2 in proper timed relation with respect to the operation of the holding shoe 4 and the wiping tongues 6.

As shown in Figs; 9 and 11, the lever 3, which carries the holding shoe 1, is pivotally mounted on a rod 60, carried by the frame of the machine, and connected by a link 61 to one end'of a lever 62,- the opposite end of which is pivotally mounted on a rod 63 carried by the frame of the machine. Intermediate its ends the lever 62 is provided with a cam follower 64L which rides in a cam groove 65 formed in a cam 66 secured to the main operating shaft 50. By this means the holding shoe 4 is operated in proper timed relation with respect to the depositing lever 2 and the wiper tongues 6, 6. As noted above the'ejecting blade 10 is secured to the arm 3 and operates therewith in timed relation to the depositing lever v2 and the wiper tongues 6. V i

As shown in Figs. 9 and 12, the wiper tongues 6 are carried by the arms 5, and the arms 5 are pivotally mounted on studs 70 carried by the frame of the machine, a portionv of which is illustrated at 71. The arms 5 are connected by links 72 to a bar/73 slidably mounted in the frame portion 71. A link 74- is connected at one of its ends to the slide bar 73 and at its opposite end to one end of a lever 75. The opposite end of the lever 75 is pivotally mounted on the rod 63 above noted. Intermediate its ends the lever 75 is 7 provided with. a cam follower 7 6 which rides in a cam groove 77 formed in a cam 78 secured to. the main operating shaft 50. By this means the wiper tongues 6, 6 are operated in proper-timed relationwith respect to the depositing arm 2 and the holdingshoe 4.
